New Phase One back announced today, using a CMOS chip for the first time, up to ISO 6400, long exposures up to an hour, liveview (would be awesome on my Technikardan) and improved frame rate whilst still 50Mp.

I reckon this will be something of a game changer, and will be the way MFD goes in the future, if they've cracked how to make bigger CMOS chips reliably it opens the door to all sorts of cool stuff.

If there is one downside the chip is a reduced size, so 1.3x crop on 645 but I am sure future versions will work on that.
 
Not spoken to anyone about cost yet, but it will certainly make for some fun testing when it comes time to replace the p45+'s that we currently use. With the improvements its going to help with some of the temptations to go back to high end DSLR or to run dual Phase and DSLR set ups.
 
I read about this, a step in the right direction although it will need to step up from 44x33 if it wants people to spend £25k on it. Is it a Sony sensor?

The IQ 250 costs $34,990 is what I read.

I would hope for some nice trade in or upgrade deals, still its going to be one to sit back and watch for a while to see what happens.

To me the sensor isn't big enough compared to say a D800E which uses roughly the same technology and the price is too high. I'd imagine there might be some nice deals on trade-in older Phase One backs though with people moving up to the IQ250. I would imagine Leica might be looking at this sensor for their new S camera or maybe even Pentax.

The sensor size and resolution is far from the only benefit of a digital back system over an SLR, being able to use technical cameras with very high levels of accuracy and lenses designed to resolve the resolution, being able to use movements far beyond those offered by TS/PC lenses, increased dynamic range, bigger photosites etc.

Yes that's a good point too, although I have been reading about people emailing dealers and getting this response:

"Phase One stated that the design of the sensor is very similar to the design of the P30+. What does this mean? Technical Camera use at wide angles is not an option with the IQ250. Extreme angles of light hitting a 5.3micron pixel covered by a micro lens create LCC issues. This might not be your medium format body if you want to use a Technical camera. But the testing will happen this week and we will get back to you on the results soon."

It's good to see the development in this market, although I've never associated medium format shooters with wanting high ISO backs. I'd imagine for landscapes etc the bigger sensors will still be king?
 
its added utility I guess, I think the pervious ones downsampled at higher iso?

Yes, sensor plus brought down the resolution considerably at high ISO.

For my usual landscapes the only real benefits of this over the other backs for me would be liveview (which would be awesome) and long exposures (which the 260 can do). For my interiors and architectural work it would be ideal, for high end wedding and portrait photographers I can see them loving this.
 
Could someone clarify if 14bit DR will mean that it will be just the same like 5D3 or at best 1DX with a larger chip size? The CCDs were 16bit, and that was the reason why they were favoured for many subjects such as landscapes. Please correct me if I am wrong.

P.S. This is a purely hypothetical question from my perspective. With prices of brand new top of the range BMW 5-series I could just about hire one for a day if I got a very big assignment.
